THE DYNAMICS OF LABOUR'S INCOME SHARES AND THE WAGE CURVE–PHILLIPS CURVE CONTROVERSY

Based on a re-parameterised Blanchflower–Oswald model this paper uses long macro-data from the OECD countries to discriminate between the Philips curve and the wage curve and examines whether there are any differences in wage dynamics between Europe and the United States. The evidence gives support for the Phillips curve and shows that wage dynamics are no different between the United States and Europe.     

THE SOURCES OF AGGREGATE PRODUCTIVITY GROWTH: US MANUFACTURING INDUSTRIES, 1958–1996

The sources of aggregate productivity growth are explored using detailed data for four‐digit US manufacturing industries during 1958–96 and a decomposition formula that allows us to quantify the contribution of structural change. Labour productivity as well as total factor productivity are considered with either value‐added or employment shares serving as aggregation weights. It is shown that structural change generally works in favour of industries with increasing productivity. This effect is particularly strong in the years since 1990, in high‐tech industries and in durable goods producing industries. The impact of the computer revolution can be clearly identified.     

GROWTH, R&D AND WELFARE: THE ROLE OF PUBLIC POLICY

This paper analyzes the normative side of an R&D growth model in which market structure and growth are jointly determined in the equilibrium of a one‐sector economy under monopolistic competition. We find that a distortion in the allocation of R&D, namely the presence of technological spillovers between firms, generates two market failures: insufficient growth and excessive entry of firms. We show that this result is driven by the interplay between market structure and growth. A simple tax/subsidy scheme to support the efficient solution is proposed.     

A REVISIT TO THE STATIONARITY OF OECD INFLATION: EVIDENCE FROM PANEL UNIT‐ROOT TESTS AND THE COVARIATE POINT OPTIMAL TEST*

This paper re‐examines the stationarity of inflation rates in 19 Organisation for Economic Cooperation and Development countries with the use of cross‐sectional information. We employ the panel unit‐root tests that allow for cross‐sectional dependency and the covariate point optimal test. These tests have high power in common due to the exploitation of cross‐sectional information, and they can assist mutually to draw a concrete conclusion on inflation dynamics for all series in the panel. Our empirical results show that allowing for cross‐sectional dependency rejects the null hypothesis that all series in the panel have a unit root, implying that there is at least one stationary series in the panel. With the help of the results of the covariate test, we can distinguish the panel into a group of stationary and a group of non‐stationary series. For robustness, the two groups of series are re‐confirmed by the panel tests. Our results reveal evidence of mean reversion in inflation for 15 of 19 countries, which is significantly stronger as compared to that obtained by the state‐of‐the‐art univariate unit‐root tests.     

边疆民族省份区域系统协调时空格局及发展机制——以云南省为例

以云南省为例,研究边疆少数民族省份区域系统协调发展演化特点。用熵值法分析1994—2008年间的时间序列、不同地域尺度的区域系统协调发展状况,得出云南省区域系统整体处于环境制约型,但处于不同发展阶段的市州其主要制约因素存在差异,区域发展总体遵循从经济制约型向资源、环境制约型转变,通过时、空角度分析发现云南省区域经济发展水平与系统协调度的关系存在一定程度的背离。应用基于VAR模型的格兰杰因果检验和脉冲响应函数剖析了云南省区域系统发展的驱动机制;并据此提出一些建议。
